The answer is C
Since we don’t know how much supplies cost in general it would be better to first find out how much the painter charges for the 5 hours
15.28 x 5 = 76.45$
Now that we know that we just need to solve for the difference. So subtract the total cost to the amount he charged for 5 hours of work
157.18 - 76.45 = 80.73
It would be 0 because as you go along it doesn't go up but keeps moving. An undefined slope is up and down/vertical.
Answer:
The identity function has a slope of m = 1 and a y-intercept of (0, 0) .
Step-by-step explanation:
The identity function is a special type of linear function having the form f(x) = x . The domain of this function is all real numbers and the range consists of all real numbers .
Median is middle number mean is the most common number and range is the difference between the smallest and biggest number

Answer:
(x, y) = (2, -2)
Step-by-step explanation:
We would normally choose to use substitution when x or y could be easily solved-for without having fractions involved. That is not the case here. However, we observe that the term 3y appears in both equations, so we can substitute for "3y" instead of "y".
From the second equation, ...
3y = 5x -16
Substituting into the first equation, ...
2x +(5x -16) = -2
7x = 14 . . . . . . . . . add 16
x = 2 . . . . . . . . . . divide by 7
Using our equation for y, we get ...
3y = 5(2) -16 = -6
y = -2 . . . . . . . . . divide by 3
The solution is (x, y) = (2, -2).
